Please help to ID

[Snaz]

I picked up this piece in a bag of tank rubble I purchased from AA and when I first placed it in my tank it slimed slightly for 4 weeks. I thought it was a goner but then it settled down and now I see new growth. I thought it was some macro algae but the slime trail leads me to think it is some kind of coral? The bulbs on the right look fine but the ones on the left look empty or even cracked open. Each bulb is about the size of a "Sugar Crisp" Any help to ID is much appreciated. Thank you.
